Shaper Machine

Shaper Machine

Process of removing metal from surface by the use of a single point cutting tool held in ram that reciprocates the tool in a linear direction across the work piece held on the table of the machine

Types of Shaper Machine

• Horizontal Shaper Machine• Ram along with tool moves in Horizontal

Direction• Vertical Shaper Machine Ram along with tool moves in Vertical Direction

Components of a Shaper Machine

Cutting Speed, Feed and Depth of Cut in Planer, Shaper and Slotting Machine

Cutting Speed, V = L*N(1+K)/1000 m/min Where L = Length of arm stroke, mm N = Number of full strokes/ minfull stroke means Working and return stroke K = Ratio of return time to cutting time

Feed f, in planing, shaping and slotting is relative movement of the tool in a direction perpendicular to primary cutting motion per full stroke , mm/stroke

Depth of Cut d, is the thickness of layer removed in one cut

Cross Sectional area of undeformed chip = t * b = f* d

f = feedd = depth of cut
